Potassium fluoride forms a thermally stable strongly hydrogenbonded complex with 4-cyanophenol. The complex is a very usefulsubstrate for the formation of biaryl ethers via denitration ordechlorination.

Dehydration of primary amides to the corresponding nitriles can be performed in aqueous micelles, without need of significant volumes of organic co-solvent. A variety of substrates, including late-stage functionalized molecules, can be converted utilizing an inexpensive, “sacrificial” nitrile which can accept an equivalent of water. Catalyst loadings of Pd(OAc)2, as low as 0.2–0.8 mol%, are possible
